+Usage: $self [option]
+
+This script applies a whitespace transformation to the commit at HEAD. If no
+options are given, then the modified files are left in the working tree.
+
+Options:
+  -h, --help     Shows this message
+  -n, --dry-run  Shows a diff of the changes to be made.
+  --amend        Squashes the changes into the commit at HEAD
+                     This option will also reformat the commit message.
+  --commit       Creates a new commit containing only the whitespace changes
+  --msg-only     Reformat the commit message only, ignore the patch itself.
